To all whom t may concern.

zen of Germany and 'resident of Berlin,

in the State of l have invented certain new and useful Imrovements in Aparatus for Makin Food roducts from (iain, of which thel ollowinis aspecification.

y invention relates to improvements in l0 apparatus for making foodproducts from ain, and more particularly in agpsratus or se aratin fromthe am the usks by first orou y washing e grain bymeans of water w ilestirring the same within a 16 suitable vessel, thereafter soaking thegrain with water at elevated temperature preferably at a temperature of60 to 65 while stirring and beatmg the same for gradually separatingtherefrom the hu removing the separated husks from the mass of grain,disintegrating theI grain separated from the husks, and working thegrain intol food products. Y I I have foundv that by thus treating thegrain I am enabled to remove therefrom the undi estible matter and moreparticularly the usks mainly consistin of cellulose,

while the digestible parts an more particularlyI those containing thecarbohydrates l0 (starch) andl the albumen luten) enter almost withoutloss into the Ifreed roduct. The dough thus obtained can be coo ed intobread or into food preserves and more par. ticnlarly food roducts whichare in a. dry state and whic therefore lcan be stored for any length oftime without losing their good taste and digestibility. Dry foodreserves thus made from the mass obtains b the aforesaid process areparticularly suitab e for 0 use in hospitals, for tourists use and thelike,

by -reason of their high nourishing property.

Gne of the objects of the improvements is to provide an apparatus forcan-yin out the aforesaid process, by means of w ich 5 the husks arespeedily separated from the grain, and which requires comparativelyittle power. With this obect in view my invention consists in provi inga plurality of beatin members within a vessel or l trough, which membersare mounted for hav- Guess, a citissia, German Empire,V

ing planetary movement and which therefore revolve about a common axisand in addition perform rotary movement each about its own axis. TherebyI ain enabled to construct each beating member with comparatively smalldiameter, so that itreguires a minimum of power. Notwithstand-l ing thissubstantially the whole area of the trou h is subject to the beatiaction of the ating members. The revo ving move ment ispeculiar inthatAthe consistency and amount of material treated afecte the speed ofthe movement.

Another object of the improvements is to provide novel drivingbemeansfor the beating and stirring mem rs, the object be' to provide drivinmeans which are simp e in construction. ith this object in view myinvention consists in mountin the beating and stirring membersvertically and T0 parallel to each other, so that they are passed intothe vessel or trough from above. Other objects of the improvements -willbe understod from the following description.

In order that my invention be more clearly understood 'an exam leembodying the same has been shown in t e accompanying drawings, in whichthe same reference characters have been used in all the views toindicate corresponding parts. In said drawings,
